THEODORE KOLLME, OF Er ST ST. LOUIS, ILLINOIS.

DOOR-FASTENER.

SPECIFICATION forming part of Letters Patent No. 787,847, dated April 18, 1905.

Application filed November 17, 1904. Serial No. 233,056.

To nl/ n'imm/ if may concern:

Be it known that I, Tnnoponn KoLLnn, a citizen of the United States, and a resident of East St. Louis, Illinois, have invented certain l l i I My invention relates to door-fasteners; and

it consists of the novel features herein shown, described, and claimed.

In the drawings, Figure 1 is a perspective of a door-fastener embodying the principles of my invention. Fig. 2 is a sectional detail showing the door-fastener applied to a door, the door-frame and door being broken away to economize space. Fig. 3 is a side elevation of the door-fastener in its open position and removed from the door, the view being taken looking in the direction indicated by the arrow 3 in Fig. Fig. t is an edge view of the door-fastener as seen looking in the direction indicated by the arrow in Fig. 3. Fig. 5 is a view analogous to Fig. 3 and showing the parts in ditferent relative positions.

eferring to the drawings in detail, the plate 6 has teeth T extending at right angles from one end and hinge members 8 extending from the other end, there being a screw-opening 9 through the plate near the teeth 7 and there being a vertically-elongated opening 10 between the screw-opening and the hinge mem bers.

The plate 6 is adapted to be inserted when applied to a door against the door-casing 11, so that the edge of the door will engage the plate and press the teeth 7 into the door-casing. A screw I2 may be inserted through the opening 9 into the doorcasing when it is desired to attach the fastener permanently in position. and when the fastener is only to be i used over night the screw 12 may be omitted. If desired, the plate 6 may be applied to the lower meeting-rail of the upper sash of a window instead of to the door-casing.

The plate 13 has hinge members 1a, which intcrmesh with the hinge members 8, and a hinge-pin 15 connects the two sets of hinge members together, there being a vertical slot 16 through the plate 13. The plate 17 is slidingly connected to the plate 13 by a rivet 18, inserted through the slot 16 and Iixed in the plate 17. The stops 19 extend from the plate 17 to engage the door or the upper rail of the lower sash and prevent opening, said arms also being used as handles. The metal cut from between the arms 19 is turned inwardly and cut short to form the button 20, said button being adapted to pass through the opening 10 and button into said opening by sliding the plate 17 up or down, there being teeth 21 extending from the button to engage inside of the plate 6. W'hen the door is to be left free to open without removing the door-fastener, the arms 19 are operated to disconnect the button from the plate 6. Then the plate 17 is swung outwardly to bring the arms 19 out of the way of the door or window-sash. \Vhen it is desired to fasten the door or window, the door or window is moved to its closed position and the plate 17 swung to its closed position and buttoned. It is obvious that the door or window cannot then be opened from the outside.

A door-fastener embodying the principles herein set forth is portable, light, and inexpensive and very effective in operation.

I claim In a door-fastener: a plate having a central opening; teeth extending from one end of the plate; a second plate hinged to the other end of the first plate; a third plate slidingly connected to the second plate; a button carried by the third plate to engage in the opening of the first plate; and stops extending from the third plate.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.

T I-IEODORE KOLLME.
